module to the tree shall be achieved
using a single 12 way flexible hose
bundle. At the control module end
each hose bundle shall terminate onto
a common stabplate. At the opposing

hydraulic lines to the respective tree
function.
Note: Welded connections shall be
used wherever possible on all
hydraulic and chemical injection lines.
The tree vendors shall ensure
that all hoses/bundles and
hydraulic tubing are
adequately clamped/tied to
prevent damage resulting from
vibration due to high seabed
currents.
The controls vendor shall
supply the fixed bulkhead
plate fully populated with
couplers complete with

visual indication of stem travel.
Valves shall have bi-directional
sealing with metal-to-metal seals on
the downstream gate/seat/body
interface.
Note: Vented couplers for the
following tree functions shall

stabplate to ensure the valve
control lines remain free of
trapped pressure and valves
can failclose once outboard
production stabplate or
workover plate is removed:-
